Abstract

Background Peripheral artery disease (PAD) is both a common comorbidity and a contributing factor to heart failure. Whether PAD is associated with hospitalization for recurrent decompensation among patients with established heart failure is uncertain. Methods and Results Since 2005, the ARIC (Atherosclerosis Risk in Communities) study has conducted active surveillance of hospitalized acute decompensated heart failure (ADHF), with events verified by physician review. From 2005 to 2016, 1481 patients were hospitalized with ADHF and discharged alive (mean age, 78 years; 69% White). Of these, 207 (14%) had diagnosis of PAD. Those with PAD were more often men (55% versus 44%) and smokers (17% versus 8%), with a greater prevalence of coronary artery disease (72% versus 52%). Patients with PAD had an increased risk of at least 1 ADHF readmission, both within 30 days (11% versus 7%) and 1 year (39% versus 28%) of discharge from the index hospitalization. After adjustments, PAD was associated with twice the hazard of ADHF readmission within 30 days (HR, 2.02; 95% CI, 1.14-3.60) and a 60% higher hazard of ADHF readmission within 1 year (HR, 1.60; 95% CI, 1.25-2.05). The 1-year hazard of ADHF readmission associated with PAD was stronger with heart failure with reduced ejection fraction (HR, 2.01; 95% CI, 1.29-3.13) than preserved ejection fraction (HR, 1.04; 95% CI, 0.69-1.56); for interaction=0.05. Conclusions Patients with ADHF and concomitant PAD have a higher likelihood of ADHF readmission. Strategies to prevent ADHF readmissions in this high-risk group are warranted.
